Instead of feeling a painful prick as the needle goes in, you watch it touch your skin but feel nothing.

That's how a revolutionary new needle works: It first injects you with a tiny amount of local anesthetic, which masks the pain inflicted by the bigger needle.

Okay, so the first injection is not entirely painless, but "virtually pain-free," says the BBC.

It quotes the needle's inventor, UK-based 29-year-old designer Oliver Blackwell, who says the first prick is "like a fly landing on your palm."

Still, the new needle is a big improvement on the current method of creating pain-free injections: "At the moment, if they want to use a local anesthetic they have to use two needles, find keys and go to the medicine cupboard separately and it all takes time and effort," Blackwell says.

Blackwell got help with his design, which looks like a regular injection needle, from two family doctors and a former president of The Royal College of Anaesthetists, who helped him make it easy to use.

While millions of people would love to for their shots to become pain-free immediately, the new needle must go through more tests before it can be mass-produced.
